Title:
AIR COMPRESSOR APPARATUS
Document Type and Number:
WIPO Patent Application WO/2014/121497
Kind Code:
A1
Abstract:
An air compressor apparatus comprising a machine case body (1). Same has arranged therein an air compressor. A motor (21) drives a piston head (26) of a piston body (25) to move reciprocatively within a cylinder (3), thus allowing compressed air in the cylinder (3) to be pushed into an air storage base (5). The air storage base (5) is provided with several manifolds (52, 53, and 55) that can be in communication with the air storage base (5). A duct (54) of a secondary air chamber (541) is provided on the outer wall of the cylinder (3). The secondary air chamber (541) is in communication with a compression chamber (33) of the cylinder (3) but is not in communication with the air storage base (5). When the top surface of the piston head (26) of the air compressor is completely abutted against the inner wall surface of the compression chamber (33) of the cylinder (3), partially compressed air enters the secondary air chamber (541). This not only allows for increased smoothness in downstrokes of the piston body (25), but also allows the air compressor to obviate the need for a pressure safety valve to be provided additionally to prevent an inflation movement that exceeds a safe pressure value range from occurring.
